Description
Bei Ständerblechpaketen von Kleinmotoren wird das aus einzelnen Blechen geschichtete Paket, das vorzugsweise verstärkte Endbleche erhält, durch Niete zusammengehalten. Um den Aufbau des Motors zu vereinfachen, hat man die Lagerstellen ■ (Lagerschild, Lagerbügel) unmittelbar an dem Blechpaket befestigt. Hierbei ist es erforderlich, da die Bleche nicht überall genau gleiche Stärke besitzen, durch Einrichten eine einwandfreie Befestigung der Lagerstellen zu gewährleisten, damit ein Klemmen der Welle vermieden wird. Zur Vermeidung des beim Zusammenbau erforderlichen Einrichtens sind bereits Ständerblechpakete mit einer planparallelen Metallumgießung oder Um-In the case of laminated stator stacks of small engines, the stack of individual laminations, the preferably reinforced end plates are held together by rivets. To build the To simplify the motor, you have the bearing points ■ (bearing plate, bearing bracket) directly on the Laminated core attached. It is necessary here because the sheets are not exactly the same thickness everywhere own to ensure proper attachment of the bearings by setting up so jamming of the shaft is avoided. To avoid the need for assembly Set up are already sheet metal stacks with a plane-parallel metal encapsulation or encapsulation

Gegenstand der Erfindung ist ein genietetes Ständerblechpaket zur unmittelbaren Befestigung der Lagerstellen, bei welchem ein besonderes Einrichten bzw. ein Umspritzen entbehrlich ist. Ge-The invention relates to a riveted stator core for the direct attachment of the Storage locations in which a special set-up or overmoulding is dispensable. Ge

Dadurch gelingt es, eine einwandfreie BefestigungAo measure of the invention are the end plates with edges provided and their end faces machined plane-parallel so that they are completely flat and one below the other are parallel and exactly perpendicular to the axis. This makes it possible to achieve a perfect attachment
as der Lagerstellen zu erzielen. Besonders zweckmäßig ist es, die Bleche an den Befestigungsstellen für die Lagerstellen durch Klammern starr und fest zusammenzuhalten, um zu vermeiden, daß sich die Länge des Blechpakets beim Zusammenbau mit den Lagerstellen ändert.as of the storage locations. Particularly useful is to rigidly attach the metal sheets to the mounting points for the bearing points and by means of brackets hold tightly together to avoid that the length of the laminated core during assembly with the depository changes.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt Fig. ι das fertige Blechpaket in Ansicht, Fig. 2 das Paket im Schnitt,In the drawing, an embodiment of the invention is shown, namely shows Fig. Ι the finished sheet package in view, Fig. 2 the package in section,

Fig. 6 und 7 die Klammern.Figures 6 and 7 show the brackets.
Wie aus Fig. 5 hervorgeht, besitzen die gestanzten Bleche 1 Löcher 2 zur Aufnahme der Niete und Löcher 3 für die Aufnahme der Be-. festigungsbolzen der Lagerstellen. Oberhalb der letztgenannten Löcher sind schwalbenschvvanzförmige Ausnehmungen 4 eingestanzt. ^ Die Endbleche 5 . (vgl. Fig. 3 und 4) besitzen. einen Rand 6. Die Bleche 1, die beispielsweise 0,5 mm stark sind, werden aufeinanidergeischichtiet. Nach Anbringung der Endbleche, die ungefähr 1,5 mm stark sind, werden durch die Löcher 2 Nietbolzen 8 eingezogen und die Bleche zusammengenietet. Hierauf wenden die Klammern 9, die in Fig. 6 und 7 dargestellt sind, in die schwalbenschwanzfönmijgen Nuten 4 der Bleche eingelegt und durch Druck aiuseinaaidergepreßt, so daß die Bleche fest zusammengehalten werden. Außerdem werden die Klammern am Ende umgebogen, so daß auch die Endbleche an diesen Stellen gehalten werden. Diese besitzen, da sie mit einem Rand versehen sind, keine schwalbenschwanzförmigen, sondern rechteckige Ausnehmungen 7, über welche die Klammern, die Ausnehmungen 10 für die Bolzen besitzen, umgebogen werden. Durch die Vernietung der Bleche und durch die Anwendung der Klammern, die sich mit den einzelnen Blechen seitlich sehr fest verkrallen, wird ein sehr starres Blechpaket erzielt, dessen Länge auch beim Zusammenbau mit den Lagerschildern unveränderlich ist. Nach der Vernietung und Verklammerung des Blechpaketes werden die Stirnflächen der Endbleche planparallel durch Abdrehen oder Abschleifen bearbeitet. Auch kann, wenn erforderlich, ein Abdrehen oder Abschleifen der Endblech» am äußeren Umfang erfolgen, um eine genau zentrische Befestigung der Lagerstellen zu erhalten. Im allgemeinen wird dies aber bei gezogenen Endblechen nicht notwendig sein.As can be seen from Fig. 5, the punched sheets have 1 holes 2 for receiving the Rivets and holes 3 for receiving the loading. mounting bolts of the bearings. Above the The latter holes are dovetail-shaped recesses 4 punched. ^ The end plates 5. (see. Fig. 3 and 4) have. an edge 6. The sheets 1, for example 0.5 mm thick are layered on top of one another. After attaching the end plates, which are approximately 1.5 mm thick, through the holes 2 Rivet bolts 8 drawn in and the sheets riveted together. The brackets 9, which are shown in 6 and 7 are shown, inserted into the dovetail grooves 4 of the sheets and aiuseinaaidergepreected by pressure, so that the sheets be held together tightly. In addition, the brackets are bent over at the end, so that too the end plates are held in these places. These own because they are provided with a border are not dovetail-shaped, but rectangular recesses 7 through which the Brackets that have recesses 10 for the bolts are bent over. By riveting of the sheets and by using the brackets that are attached to the individual sheets laterally claw very tightly, a very rigid laminated core is achieved, the length of which also applies during assembly is unchangeable with the end shields. After riveting and bracing the Laminated core, the end faces of the end plates are plane-parallel by turning or grinding processed. If necessary, the end plate can also be turned or ground down » take place on the outer circumference in order to obtain a precisely centric fastening of the bearings. In general, however, this will not be necessary with drawn end plates.
